Description

[Detailed description of the invention] Device for moving and cleaning filter plates in filter presses FIELD OF THE INVENTION The present invention relates to filter presses, and in particular to removing solids from liquids or relates to a press with a plurality of filter plates adapted to separate It is. More specifically, the present invention removes filter cake from plate filter cloth. remove the filter cloth and clean the filter cloth in situ on the filter plate. The present invention relates to a device for separating filter plates in a filter press.

Conventional technology Devices of the type commonly known as filter presses are known in the art. these The apparatus is used in various industries to separate solids from liquids.

Filter presses separate solids from suspensions, slurries and similar aqueous feed streams It is possible to use it to Filter presses are used for example in sewage sludge treatment It has been applied in diverse chemical and metallurgical industries such as mineral beneficiation and mineral beneficiation operations.

Filter presses typically have a plurality of separable plates. these The plate has a frame structure between the fixed support and the opposing movable support. is slidably held on top. This movable support is typically provided by a hydraulic ram. It works like this.

These plates are typically arranged parallel to the horizontal axis. each play The seat has a recess on its side surface. Above the recess is a filter cloth. The fibers are located at the end. When these plates are placed next to each other, Opposing recesses in adjacent plates form a cavity into which a fill is placed. The cloth is suspended. These plates are used to perform filtering or filtering operations. The hydraulic ram and follower plate are pressed together and mounted horizontally. A press head acting against the fixed end support on the filter and is pressed. As these plates are compressed or compressed together, each plate The plate contacts the plate next to it in a sealed manner. It is then processed The fluid or solution to be processed is transferred to various cavities defined by adjacent filter plates. It is injected into the plate via the sinus. The feed stream is surrounded by air under pressure. As it is fed into the sinus, the pressure of the feed stream forces the liquid through the filter cloth. Make it flow. As the liquid passes through the fabric, solids in the stream captured on the filter cloth.

Once the filter or filtration operation is complete, the hydraulic ram is retracted and the plates are removed one by one. The cake is separated and the cake is blown by pressurized air introduced inside the filter plate. removed from the filter cloth.

As the filter plate filters the aqueous feed stream, solids form on the surface of the filter cloth. Body material is gradually deposited. Once a certain amount is reached, these solid deposits or The key precludes operation or use of the filter. Continue using the filter press. To separate the filter plates from each other and remove the cake from the filter cloth. Finally, solid deposits must be removed.

Afterwards, it is desirable to clean the filter cloth in the field. This means that the market The process involves a cleaning unit and a series of presses that move over the Radbeam. By providing a trolley system that can be designed to This is done in a shifter or mover. The cleaning unit is overhead When moving along the beam, the spray head is in a retracted position. the press is opened And the movable helad or follower is returned to the position between the first two plates. When the cleaning unit is opened, the cleaning unit is activated. The spray head descends and then It moves up between the two plates that form the first chamber, and as it moves, the spray Perform spraying.

The filter cloth covering these two opposing plates has between 24 and 40 nodes. Receive high-pressure water spray from Zul. The speed of movement of the spray head is adjustable.

After the spray head is retracted, the cleaning unit is positioned to treat the second chamber. Move along the radbeam over until you reach the position. In automatic operation, washing The movement of the cleaning unit is synchronized with the action of the plate moving body, and the movement of the plate moving body is synchronized with the action of the plate moving body. opens the rooms one by one. In semi-automatic operation, the action of the cleaning unit is Dant controlled.

In such cleaning units, a pair of long vertical guide rods guide the spray head. It is attached to the rad beam and can be moved along the rad beam to the fixed over. It is guided through a hole in the member. In the retracted position, the rod and spray The head is moved to a position above the plate so that it can be used for subsequent cleaning. It is possible to move between different sets of plates for cycles. water The dispersion line has a pair of elongated bellows-like tubing that are retracted. The spray head moves downward to spray the facing fiber cloth. Each horizontal increment is extended when scattering. The configuration described above is Example of a scourshower washer It is shown.

Other filter cloth washers are wound onto an upper horizontal cable drum and At the same time, the spray bar is lowered and raised by the cable fed out from the Sometimes the spray head is configured to wash both sides of one plate.

Separate filter plates from each other to facilitate cleaning of filter cloth Apparatus and methods for detecting oxidation are problems that have faced the industry for many years.

Conventionally, when separating the plates in the filter press after filtering Various attempts have been made to create automated separation systems for use in .

Representative of some of these attempts is U.S. Pat. No. 4,102. No. 788 (Broad), U.S. Patent No. 4.359.385 (Krivec), U.S. Patent No. 3.915.863 (Busse et aj7.), U.S. Pat. No. 3.232.435 (Fi sme r), U.S. Patent No. 4,272 No. 376 (Schotten), U.S. Patent No. 4,132.647 (Sakum a), U.S. Patent No. 4.105.560 (Fismer), etc.

In a related application, a rodless cylinder is mounted on the bottom side of the filter press frame. extending horizontally along and coupled with the pawl subsystem to release, dirt, and movement of a plate with fibrous media, i.e. with a residual filter cake attached. , detaching the filter cake from each plate by air blowing, and detaching the cake. gives the movement of the plate to the follower. Remove cake from all plates After this, the follower is activated and the stack of plates is activated. The feed slurry is then reformed to abut each other and ready for the start of the subsequent filter cycle. Preparations will be made.

Summary of the invention The present invention provides the following features: A pair of horizontal rodless cylinders or frames extending along the longitudinal axis. Concerning a filter press having a plurality of slidably mounted filter plates It is something that

The plate is suspended from and above a stationary guide rail or guide track. can be slid freely.

The automatic filter plate mover of the present invention is arranged near the opposite upper ends of the filter plate. It has guide tracks located adjacent to each other. This guide track is press oriented substantially parallel to the longitudinal axis path of the filter plate within the filter plate. tree a carriage is slidably mounted on the guide track; adapted to reciprocate on a track, along which it moves forward and backward; both in the rearward direction, for example about 50 cm, along substantially the entire length of the filter. Move in increments. The carriage has a third pawl, which is attached to the carriage. Positioning is possible in two orientation states or conditions on the top. First orientation or row In this case, the pawl is raised above the surface of the carriage. In the second orientation state In this case, the pawl is positioned substantially below its first orientation. In some cases , the pawl is located below the top surface of the carriage itself. The claw is attached to the carriage. It is rotatably mounted and can reciprocate between the first and second orientation states.

a flexible support means is mounted on the carriage and associated with the pawl; The support means biases the pawl into its node-1 or raised orientation.

The first contaminant plate pickup pawl has an abutment surface (1) that catch the far end of the plate at the bottom of the rate handle; and (2) It laterally pulls the plate into the cleaning position with the pick-up claw rising condition. . The pawl pivots upwardly to catch the far side of each successive plate. It is biased by a spring.

When the carriage is displaced in the first direction, the caught abutment surface transmits the momentum of the filter plate to the filter plate, and at the same time The actuator acts to pull and cause a corresponding displacement of the plate into the cleaning position. Ru. When the first pawl sliding surface comes into contact with the contaminated first plate, the contact causes the second - the pawl is shifted from its raised condition to its lowered condition; This descended condition, the abutment surface is substantially free from pick-up contact with the filter plate. separated into. The sliding surface is such that the pawl has one or more sliding surfaces under its lowering condition. Allows displacement in a direction beyond the filter plate. pass through the plate The claw then returns to its raised orientation. Next, reverse the direction of the claw movement. i.e. by moving in the first direction so that the abutting surface touches the filter plate. come into contact with. Further displacement of the carriage-pawl assembly causes the carriage-pawl assembly to Displacement of the filter plate occurs in the direction of movement.

At the same time, the second bush pawl is pushed outward by the spring and is in the cleaning position. catch the corresponding edge of the cleaned plate and remove the contaminated plate. The movement of the carriage and the third pawl that simultaneously pull the cleaned plate direction of the plate, placing each washed plate in sequence against the follower plate. Stack or laminate. Once the carriage stack is complete, the cleaning mechanism cleans the carriage. When interconnected to the ridge, a cleaning cycle begins.

stacked against the next contaminated plate and follower in the filter stack An overall opening of 20 inches between the last plate to be cleaned will prevent contamination. The dyeing plate was moved 10 inches to the washing position, and the washed plate was placed in the wash position. Moved 10 inches against the tack. When the wash cycle is complete, the carriage is moved in the opposite direction and the second mold is rotated to the "down" position, so it is in the cleaning position. It is possible to move the underside of the cleaned plate in the Return to pick up the next contaminated plate in the router plate stack do.

The second mold is then raised after passing through the cleaned plate, and the second pawl is moved up for the next stain. When picking up a dyed plate, place the washed plate against the follower. Positioned to tshu.

In a preferred arrangement, both the first and second types of pivot mountings substantially rotate the pawl. Allows rotation around a horizontal axis. Furthermore, the rotation axis is a filter tab. oriented substantially perpendicular to the longitudinal axis of the frame of the res. The nail is a carrier. parallel to the longitudinal axis of the edge and the longitudinal axis of the frame and along the guide track. The carriage rotates in a vertical plane parallel to the direction of movement of the carriage. th nail Similarly, the second type also has flexible support means associated with it, which It is adapted to bias the mold into its first or elevated orientation.

As shown in related applications, the carriage is mechanically associated with drive means. . Preferably, the drive means is a piston, the piston being a rodless cylinder. It is reciprocatably mounted in a cylindrical member. The cylindrical member is attached to the flange of the filter press. connected to the system. The cylindrical member has a side wall, and the side wall has a filter plate. extending longitudinally along the length of the frame of the frame. The cylindrical member is Two opposed pressure chambers are defined within the cavity.

A drive piston is located between these pressure chambers.

When the pressure changes in these two pressure chambers, the piston moves inside the cylindrical member. The displacement or reciprocation of the piston causes the carriage to move along the guide track. generates a corresponding displacement of the ji.

The tubular member defines a slotted aperture extending along its length. bracket The piston is attached to the carriage member and is slidably fitted into the slot. has been done. The tubular member remains in the slot during movement of the piston therein. Means for sealing is fitted. This seal creates two opposing pressure chambers. can be pressurized and generate a displacement of the piston within the cylindrical member.

Introducing pressurized fluid into any of the pressure chambers defined within the tubular member is a matter of concern. It is operated by a control system as shown in the co-pending application. This control system Pressurized fluid is controlled to displace the carriage in either direction.

When the contact surface of the third claw is brought into contact with the first plate, the contact surface is brought into contact with the first plate. The filter plate is then introduced into the space between the two opposing claws.

The filter plate is placed next to the filter plate against a rigidly positioned support. Adjacent to a series of plates, it allows continuous flow of pressurized fluid into the pressurized chamber. , without causing a corresponding displacement of the filter plate. Pressure is reinforced. When the pressure in the pressure chamber increases and exceeds a preselected value, the control A control system introduces pressurized fluid into a second or opposing pressure chamber within the tubular member.

The pressurized fluid in the previous or first pressure chamber is discharged. Introducing pressurized fluid into the second pressure chamber By injecting air into the first pressure chamber, the Displacement of the ridge occurs.

The arrangement of the claws is such that when these claws come into contact with the filter plate, allows the pawls to form a releasable association with the respective filter plate Ru.

The carriage is driven by the piston with sufficient force to absorb the pressure introduced into the first pressure chamber. Transforming the filter plate along a first direction opposite to that induced by the pressure fluid place.

All of the plates can be removed from the loading or compressed position for cleaning. Transfer the cleaned plate to the open configuration and then stack the cleaned plate against the follower plate. until transferred to the opposite end of the filter press frame for cleaning. The operation is subsequently repeated for each filter plate.

The guide track of the invention is arranged adjacent to the filter plate, i.e. along the longitudinal axis of the filter press. and can extend substantially parallel to each other. Guide track is stuck can be positioned above the filter plate in an array, while It is possible to extend substantially parallel to the longitudinal axis of the filter press. good In a suitable configuration, the guide track, together with associated carriage and drive means. are located on each side of the filter plate, moving the plate from one position to the other. It forms a joint conveying means for conveying the material to the position.

The present invention provides for vertical translation using the plate mover for horizontal translation as described above. We offer a portable filter cloth washer. This washer is used during normal press operation. During the process, the follower plate is parked between the press head and the plate. When cleaning, the follower plate is retracted and the cleaner is manually removed from the mover carrier. Locked inside the ridge. A pendant switch allows you to switch off the key to which the washer is attached. The carriage removes the first contaminant from the compressed stack by the action of the first pick-up pawl. Pick up the plate and move the contaminated plate to the cleaning position. wash The cleaning cycle can be performed automatically or by operation of the up/down pendant switch button. It starts. Once the cleaning operation is complete, the mover carriage will move automatically. Pick the next plate or be moved by pendant switch action while the second mold slides under the handle of the cleaned plate. First pi At the same time as the pick-up claw pulls the contaminated plate to the cleaning position, A previously washed plate is pushed into the follower stack by a second wind. . The chamber stack is separated from all mechanical components and therefore risks of contamination will not occur. The washer was mounted vertically of the same type as the mover. A rodless pneumatic cylinder is used, which is the aforementioned Schreiber (Sh filter plate required by the traditional movable guide rod of the washer Substantial overhead clearance space above the beams and beams There is no need for it. Horizontally positioned water spray that can be moved vertically The nozzle array is movable in juxtaposition to the contaminated surface of the filter plate and thus The water impinges on the fiber filter cloth and removes the remaining cake from the plate filter cloth.
